I claim:

1. In a measuring. cup of the character described, wherein thecup has anannular side wall and an end wall, wherein a rod rotatably and slidablyextends through the end wall, wherein an adjustable false bottom for thecup is fixed to the inner end of the slide rod and wherein cooperatingmeans are carried by thee'nd wall of the cup and slide rod forholdlngnthefalse bottom in adjusted position, a scraper blade freelymounted on the false bottom in contactwith the exposedside, thereof andsaid scraper blade having a sliding interlockingconnection with theannular. side wall of. the cup whereby the false bottom may be rot atedby the slide .rod with the scraper blade remaining stationary. V,

2. In a measuring cupof the character described, wherein the cup has anannular side wall and an end wall, wherein a rod rotatably and slidablyextends through the end wall, wherein an adjustable false bottom forthecupis fixed to the inner end of the slide rod and wherein cooperatingmeans are carried by the end wall of the cup and slide rod for holdingthefalse bottom in adjusted position, a scraper blade freely mounted onthe .false bottom in contact with the exposed side thereof andcomprising a wall and an end wall, wherein a rod rotatably and slidablyextends through the end wall, wherein an adjustable false bottom for thecup is fixed tothe'inner end of the slide rod and wherein cooperatingmeans are carried by the end wall of the cup and slide rod for holdingthe false bottom in adjusted positions, a scraper blade freely mountedon the falsebottom in contact with the exposed side thereof andcomprising a metallic strip having upwardly and inwardlydirectedlreturn-bent ends overlying the false bottom with the upwardlybent ,end portions of the strip projecting outwardly of the peripheraledge of the false bottom, the inner face of the side wall of the cuphaving-diametrically,oppo site horizontally extending grooves thereinfor the sliding interlocking reception of the outwardly projecting endportions of the strip.
